    摘要:
    摘要从绿色木霉纤维素酶复合物中部分纯化了一种新的β-葡萄糖苷酶。该β-葡糖苷酶水解β-(1→2)-,β-(1→3)-,β-(1→4)-和β-(1→6)-连接的葡糖苷酶并催化纤维二糖的转糖基化反应。产生区域选择性的β-d -Glc-(1→6)-β-d-Glc-(1→4)-d -Glc(产率:18.8%)和β-d -Glc-(1→6)-β -d -Glc-(1→6)-β-d-Glc-(1→4)-d-Glc(3.7%)。此外,该酶将laminarabiose和龙胆二糖转化为β-d -Glc-(1→6)-β-d-Glc-(1→3)-d -Glc(15.3%)和β-d -Glc-(1→ 6)-β-d-Glc-(1→6)-d-Glc(20.2%)。产物的结构通过1 H和13 C NMR光谱确定。该酶显示的这种高区域选择性和立体选择性通常可用于寡糖合成。

    and gentiobiose into β- d -Glc-(1→6)-β- d -Glc-(1→3)- d -Glc (15.3%) and β- d -Glc-(1→6)-β- d -Glc-(1→6)- d -Glc (20.2%), respectively. The structures of the products were determined by 1 H and 13 C NMR spectroscopy. This high regio- and stereoselectivity demonstrated by the enzyme could be applied for oligosaccharide synthesis in general.

  • Transglycosylation of cellobiose by partially purified Trichoderma viride cellulase
    作者:Hiroyuki Kono、Markus R Waelchli、Masashi Fujiwara、Tomoki Erata、Mitsuo Takai

    日期:1999.6
    A commercial cellulase from Trichoderma viride was fractionated into three fractions, F1, F2, and F3, in order to investigate transglycosylation activities. Among these fi actions, F3, which demonstrated highly hydrolytic activity toward p-nitrophenyl P-D-glucopyranoside and Avicel, most effectively catalyzed the transglycosylation of cellobiose and converted cellobiose into beta-Glc-(1 --> 6)-beta-glc-(1 --> 4)-Glc and beta-Glc-(1 --> 6)-beta-Glc-(1 --> 6)-beta-Glc-(1 --> 4)-Glc. The F3 fraction contained the enzyme to catalyze beta-glucosyl transfer toward only the C-6 position of the sugar acceptor, and thus it is expected to be of use for syntheses of functional oligosaccharides.

  • Regioselective Syntheses of New Tri-and Tetrasaccharides by Transglycosylation of Trichoderma Viride β-Glucosidase
    作者:Hiroyuki Kono、Shin Kawano、Tomoki Erata、Mitsuo Takai
    DOI:10.1080/07328300008544070
    日期:2000.1
    A new beta-glucosidase, which was partially purified from Trichoderma viride cellulase, catalyzed a transglycosylation reaction of cellobiose to give beta-D-Glcp-(1-->6)beta-D-Glcp-(1 --> 4)-D-Glcp 1 and beta-D-Glcp-(1 --> 6)-beta-D-Glcp-(1 --> 6)-beta-D-Glcp-(1 --> 4)-D-Glcp 2, regioselectively. Furthermore, the enzyme converted laminaribiose and gentiobiose into beta-D-Glcp-(1 -->6)-beta-D-Glcp-(1 --> 3)-D-Glcp 3 and beta-o-Glcp-(1 --> 6)-beta-D-Glcp-(1 --> 6)-D-Glcp 4, respectively. Selective beta-(1-->6) transglycosylation was achieved.
